This year it’s Victoria Azarenka’s wrist, not head, that is her main physical concern.

When we last saw the fourth-ranked Belarusian at Flushing Meadows a year ago, she was being wheeled off the court after a scary collapse that was caused by a pre-match concussion. No such problems this year for Azarenka, who cruised past Johanna Larson, 6-1, 6-3 on the first match at Arthur Ashe Stadium on Tuesday.

Azarenka had been forced to withdraw from the past two tournaments at Toronto and Cincinnati because of a wrist injury, but said she was pain-free following her opening round win.

“There are always things that could have been done better, but I think had a pretty solid start,” Azarenka said. “I kept control of the match, so it’s important to have that control in the early rounds.”

Azarenka now faces Gisela Dulko in the second round — the same player she faced last year in the second round when she collapsed. If Azarenka can get past the 57th-ranked Argentinean, she faces a potential third-round showdown with Serena Williams.

Williams is seeded 27th because injuries have kept her off the court, but Azarenka would not dwell on her tough draw.

“To win these titles you have to beat the best players, so to sit and complain, it’s better to commentate or something,” Azarenka said.
